Abstract

The invention discloses a motor and a rotor core thereof. The rotor core comprises a plurality of magnetic pole parts and magnetic steel inserting parts, wherein the plurality of magnetic pole parts are distributed in a circumferential direction of the rotor core; the magnetic steel inserting parts are alternatively arranged with the magnetic pole parts one by one; any two adjacent magnetic pole parts are connected through an outer connecting part close to the outer edge of the rotor core and an inner connecting part close to the center of the rotor core; first bulge parts which protrude to the magnetic steel inserting parts are arranged at the outer connecting parts; the first bulge parts can be propped against outer side surfaces of magnetic steel inserted into the magnetic steel inserting parts; and a first air gap part and a second air gap part are respectively formed in two side parts of each first bulge part. Due to the arrangement, the rotor core of the motor disclosed by the invention is capable of solving the problems that the rotor core is liable to deform when being assembled and a magnetic steel holding space is limited.

Description

technical field [0001] The invention relates to the technical field of motors, more specifically, to a motor and its rotor core. Background technique [0002] The rotor core of the motor is composed of multiple layers of stacked steel plates, and the rotor core is provided with a plurality of magnetic pole parts and magnetic steel slots distributed along the circumferential direction. The magnetic pole parts and magnetic steel slots are arranged at intervals one by one. The magnetic steel slots are Magnet insert. [0003] Please refer to figure 1 , the outer parts of two adjacent magnetic pole parts 2, that is, the parts near the outer edge of the rotor core, are connected by the outer connecting part 3, and the inner parts of two adjacent magnetic pole parts 2, that is, the parts near the center of the rotor core The parts are connected by the inner connecting part. [0004] In order to prevent the magnetic flux of the magnetic steel insertion part 1 from leaking toward ...
